本文以城市多厅电影院的安全疏散问题为研究对象,选取上座率较高的“贺岁档”时段,实地观察调研了重庆市主城区主要的电影院,对比分析了性能化疏散设计要求相关的主体参数,进而对当前所用参数提出了修正建议。研究表明:“优惠时段”和“正常时段”对疏散人数折算率的影响不大,相反,厅堂数的影响更明显;疏散通道内的障碍物普遍存在,应对此部分进行有效宽度折减;安全出口普遍存在疏散不均衡的问题,应对应后端疏散楼梯等设施进行设计。
In this paper, the safety evacuation problem of multi-city cinema is taken as the research object. The “Lunar New Year” period with high attendance rate is selected. The main cinema in the main city of Chongqing is investigated and observed on the spot. The relevant evacuation design requirements are compared The main parameters, and then proposed amendments to the current parameters used. The results show that: “discount period ” and “normal period ” have little effect on the conversion rate of evacuees, on the contrary, the influence of number of halls is more obvious; obstacles in evacuation corridors are ubiquitous and the effective width Reduction; safety exit is generally uneven evacuation issues, should be designed to meet the back-end evacuation stairs and other facilities.
